Hello Harshit, > The tests in t4131 leave a space character between the redirection operator > and the file i.e. the redirection target which does not conform to the > modern coding style. > Fix them. I think something like, The tests in t4131 were written a long time ago and hence contain style violations such as an extra space between the redirection operator(>) and the redirection target. Update it to match the latest CodingGuidelines. may be better. Also, when you deliver a newer version of the patch, i.e., version 2 in your case, you have a [PATCH v2 1/n] as the subject, so that people know that it is the v2 and hence avoid confusion. If you are using 'git format-patch' to formulate your mails, you can do: 'git format-patch -v2 <..>' to get a v2 based mail. Regards, Shourya Shukla
